About Dropstone
Overview
Dropstone is an AI agent with a memory that follows your account across chat, the CLI, the SDK, and the editor. It started as a terminal coding agent and now also writes, researches, and places calls on your behalf.
Teach it a correction once, and it applies that memory everywhere. It also acts on what it already knows, watching tasks you assign and handing back only the decisions that need you. Blankline, a research-driven company founded in 2024, builds Dropstone.
Key Benefits
- Memory persists across sessions and model swaps, so you never start over from scratch.
- One memory applies across the CLI, chat, SDK, and editor extensions, so corrections carry over.
- Usage measurement shows what each request consumed, what it changed, and what it left behind.
- Managed inference runs with zero upstream retention, and the platform excludes enterprise and commercial data from training.
- Approval gates on every tool call keep you in control of any action the agent takes.
- Self-learning reviews past work to write rules, including what it should have caught the first time.
How It Works
Start in the terminal with the Dropstone CLI, in the browser chat, or through a VS Code, Cursor, or Windsurf extension. Teach Dropstone a correction once, and it keeps that memory across every surface and session. Review planned changes before they apply, and approve each tool call that acts for you.
Use Cases
- Software developers build and fix code from the terminal, reviewing plan-mode changes before they apply.
- Editor users work in VS Code, Cursor, or Windsurf with the same memory they use in the CLI.
- Writers and researchers ask questions, draft documents, and work through files in browser chat.
- Founders and teams share chat sessions and team memory inside a collaborative workspace.
- Individuals control smart home devices and monitor an inbox, with approval required for each action.
- Developers who rely on external tools connect them to the agent through Remote MCP connectors.
